The recorded life of Egypt reaches back more than 6,000 years; civilization in Mesopotamia may have been more ancient. Many monuments have been unearthed in the sites of ancient cities which throw light upon great antiquity. In Egypt visible monuments have borne witness through long succeeding centuries of early strength; in Babylonia and Assyria the very site of cities was forgotten, and men no longer remembered where these two influential powers of antiquity had developed. Though in the last century only anything like a complete history of Egypt has been possible, yet evidences of a nation long since extinct, were preserved in temples and tombs, and hieroglyphics covering walls and columns indicated that whoever should discover their meaning would learn of their mighty builders. Far different was the case of Babylonia and Assyria. They too had once been proud and wealthy nations, taking foremost rank; their cities filled the valleys of the Euphrates and Tigris, and their fertile fields yielded even more abundantly than the rich Nile valley. Their palaces rose to the glory of their kings, and their commerce penetrated to every corner of the ancient world. Then changes came upon the life of antiquity. New peoples pushed to the front; the tide of commerce shifted into other channels. These nations were conquered by their yet stronger neighbors, and their temples and palaces, built not of enduring stone but of perishable brick, fell into heaps of nameless mounds. When the waters of the mighty rivers were no longer guided through canals to irrigate the land, the soil ceased to be productive. Desert sands spread over the desolate region and reclaimed wide areas which became the tenting ground for nomadic tribes. The very words of the late writer in the Book of Isaiah concerning these nations rang true through the ages: "And Babylon, the glory of kingdoms, the beauty of the Chaldees' excellency, shall be as when God overthrew Sodom and Gomorrah. It shall never be inhabited, neither shall it be dwelt in from generation to generation: neither shall the Arabian pitch tent there; neither shall the shepherds make their fold there. But wild beasts of the desert shall lie there; and their houses shall be full of doleful creatures; and owls shall dwell there, and satyrs shall dance there. And the wild beasts of the islands shall cry in their desolate houses, and dragons in their pleasant palaces; and her time is near to come, and her days shall not be prolonged. "Then shall the Assyrian fall with the sword, not of a mighty man; and the sword, not of a mean man, shall devour him; but he shall flee from the sword, and his young men shall be discomfited. And he shall pass over to his stronghold for fear, and his princes shall be afraid of the ensign."[1]
